Latest Steam announcements

  • Runs great on the Steam Deck! - 28 October 2025

    We haven't officially been verified by Valve yet, but the game runs amazing on the Steam Deck. If you have one give it a try. Feels like it was made for that device. Same goes for the sequel Garden Variety Body Horror - JP. Hopefully we get our verification tag soon, but until then these posts will have to do. -a

  • Unity Security Update (and other issues) - 8 October 2025

    Unity released a fix for a security flaw found in nearly all version of Unity. As a result we've updated Prototype Mansion from Unity 2018 (was not supported in the security update) to Unity 2022 LTS. Not only did this update fix the security flaw it came with a few other added benefits. Unity Security Fix. Fixed crash found on 2nd floor caused by sleeping cat dumping animations into queue every frame. Fixed issue with elevator in Overtime not always working correctly Updated some AI pathing issues for Muriel Tweaked difficulty in Muriel's area with the nurses We will be releasing the security update for Garden Variety soon. Due to the game being larger, testing will take a little longer.

  • Episode 3: PARANORMAL PRECINCT - LAST COPY OF '99 - 26 October 2023

    Hi all! After 5 years of silence, we're damn happy to announce the final entry in our survival horror trilogy... "PARANORMAL PRECINCT - LAST COPY OF '99" The game has been quite and undertaking and as such will feature two separate game modes: Main Story Campaign: A seamless continuation to both PROTOTYPE MANSION and GARDEN VARIETY BODY HORROR that sees conclusive story endings for our heroes; Cass, Hank, and Muriel... Rookie Blues Game Mode: Solve cases, kill bosses, and save the city in this fixed-camera classic survival horror roguelite. Follow a rookie officer from the first steps of their career to their final, inevitable farewell. Experience multiple campaigns (each with 5 unique casefiles and final boss!), overcome various enemies factions, and explore many locations - rich in story and secrets. Each casefile, a milestone; each challenge, a rite of passage. All leading to the ult…

  • Last Big Update and Ep. 3 Announcement! - 24 October 2023

    Hi all, Happy Halloween! Have we got some news... Episode 3 is officially in development, more on that later though. To celebrate, we went back and did some much needed quality of life updates to both Prototype Mansion and Garden Variety Body Horror. This update brings a fix to the crash bug that so many were experiencing. Which is a huge freaking deal for us. We have been haunted by this bug for literal years. We rewrote our camera system. Overhauled every cutscene, enemy, and item with no luck. But at the end of the day… it was a cat. A simple model we used in our save system was creating a new animation clip every single frame that it wasn't on screen… and these would slowly but steadily clog up memory until the game crashed. Serves us right, honestly. Bug fixes and quality of life changes in this update: • CRASH BUG FIXED!! • "Save points" now support simple interaction • Added more…

  • Critical Bug Fixes 1/6/19 - 6 January 2019

    Released bug fixes. 1) fixed issue where the collider on some zombies would remain after killing thusly blocking your way 2) fixed issue where cat in office sometimes wouldn't appear if you killed the cat in the bedroom on the first floor 3) fixed various lighting/specular settings 4) fixed various pickup locations that had put them slightly out of reach 5) fixed issue where you could still activate doors in overtime that had been smashed down 6) fixed some controller issues... more details below. So for controller support issues. Due to how Unity and Steam interact there are some weird oddities with the controller that don't let Unity recognize it. What we've done is added an event to the game that monitors if the controller was attached subsequent times and try to re-hook it up. So if your game starts and the controller is not recognized, just unplug and replug it in. You should also…

  • Critical Bug Fix - 11/6/2018 - 6 November 2018

    Critical bug fix that resolves crashing bug that occurs on some platforms. A bug was offiliated with a Unity specific function that caused it to crash on some platforms, the issue was resolved by removing all calls to this Unity specific function.

  • Patch - Version 2.1.x.41 - 7 August 2018

    A small patch to last nights update. - FIxed bug where in Unity2018 changing the Texture Quality settings at runtime (such as when going to/from the 'Ugliest' quality setting on the title screen) causes lights to break and textures to unload. Bug was resolved by maintaining the same texture quality across all quality settings. Bug was forwarded to Unity so they can resolve the issue on their end for anyone else who uses Unity2018.

  • Patch/Update/New Platform - Version 2.1.x.40 - 6 August 2018

    Tonight we're releasing support for MacOS! Included are also some slight bug fixes, including an upgrade to Unity that should have resolved the crashing bug some people were having. -Added support for MacOS. -Updated to Unity 2018.2.1 - this should resolve the crashing issue some people were having. -Slightly changed cat tutorial. -Fixed zombie SFX not playing sometimes. -Fixed save bug in hidden room where if you save after finding muriel but die before entering muriels level some weird things start to happen in game due to order mismatch

  • Patch/Update - Version 2.1.x.38 - 28 July 2018

    Tonight we're releasing a patch to the game. We've released a couple previously this week but didn't release patch notes (we apologize for that). So to cover the past update we added: -Overtime rebalanced based on feedback (beefed up finale, tweaked enemy spawns, added more stockpiles, additional key cutscene added) -Added a knockback to doors in Overtime to reduce enemy's ability to instagrab you when entering a room for the first time (they still can, it'll just happen way less often now) -Swapped out overly loud SFX from one cutscene -Made dodge a little more useful -Fixed a bug where the secret S-Rank unlockable weapon would spawn with no ammo -Fixed a bug where some HARD mode enemies were spawning in EASY and NORMAL mode -Fixed a bug where some achievements were unachieveable (S-Rank, tank mode, hockey, docs) -Fixed a bug where you could become trapped in the secret room in overtim…

Price History Overview

USD uses SteamPulse's own locally recorded daily store snapshots, so this overview reflects the exact regional price history that SteamPulse has captured for this currency.

Coverage And Tracking Window

  • Snapshots: 1
  • Coverage: Sep 23, 2026 to Sep 23, 2026
  • Lowest observed: $4.99
  • Highest observed: $4.99

Prototype Mansion - Used No Cover's USD price history spans from Sep 23, 2026 to Sep 23, 2026, with 1 recorded snapshot across 1 calendar day. Each row records the available final price, listed base price, and discount metadata for that observation. Within this coverage the lowest recorded price is $4.99, the highest is $4.99, and the first visible tracked price is $4.99. These comparisons apply only to the snapshots SteamPulse holds; missing observations can contain changes that are not represented here.

For USD, SteamPulse uses locally captured regional storefront snapshots and does not reconstruct older prices with exchange-rate conversion. The chart and table show the values recorded for this exact currency from the stated coverage start. Additional snapshots extend that record, but they do not fill unobserved days or prove what the storefront displayed between observations.

Discount Windows And Sale Timing

  • Discount windows: 0
  • Discounted days: 0 days
  • Deepest markdown: No discount tracked
  • Latest sale window: No sale window tracked

Prototype Mansion - Used No Cover's tracked USD rows do not contain a discount window. This means no available snapshot in the stated coverage has usable discount metadata; it does not prove that the game was never discounted. Missing snapshots or archived rows without complete metadata can hide a sale, so SteamPulse does not infer pricing strategy from this absence.

If a later snapshot includes discount metadata, it will appear here with its recorded depth, price, date, and sale name when available. Until then, this section should be read only as a description of the available rows, not as evidence about the publisher's promotion policy.

Observed Price Changes And Stable Runs

  • Observed price drops: 0
  • Observed price rises: 0
  • Longest stable run: 1 day of uninterrupted daily tracking
  • Current run: 1 day of uninterrupted daily tracking

Outside rows carrying discount metadata, the tracked price has not recorded a separate price rise or drop yet. That means the observed undiscounted level has stayed stable across the snapshots SteamPulse currently holds. This is a statement about the recorded coverage only; it does not prove that an older or missing price change never happened.

The longest unchanged price stretch in the current record lasts 1 day of uninterrupted daily tracking at $4.99, from Sep 23, 2026 through Sep 23, 2026. Among rows without discount metadata, the longest unchanged run lasts 1 day of uninterrupted daily tracking at $4.99. The latest run records $4.99 for 1 day of uninterrupted daily tracking as the same recorded undiscounted price. Run lengths describe consecutive stored observations only and do not establish that a price is permanent.

Latest Snapshot And Sales Context

  • Current price: $4.99
  • Current list price: $4.99
  • Distinct observed prices: 1
  • Source mode: SteamPulse local tracking

The latest tracked snapshot records Prototype Mansion - Used No Cover at $4.99 in USD, with no active discount metadata. Across the available history SteamPulse has recorded 1 distinct final price in this currency. This supports comparisons with the lowest, highest, and most common values present in the retained record, subject to the stated coverage limits.

The live sales view and Steam sales record provide calendar context for these dates. A date overlap can be compared with a named Steam event, but it does not prove why a publisher changed a price. As new daily rows arrive, this overview recalculates its observed prices, discount windows, and run lengths automatically.
